Physics for IGCSE & O level - Forces And Motion (Section 7 - No. 14)
What happens to an object's motion if the net force acting on it is zero?
The object accelerates in the direction of the force.
The object stops moving.
The object's velocity remains constant.
The object changes direction.
Açıklama
If the net force is zero, the object either remains at rest or moves at a constant velocity (Newton's First Law).
